I have
render() {
return <AppBar style={{ position: "fixed" }} title={<span>my Title</span>}
iconElementLeft={<IconButton><NavigationMenu /></IconButton>}
iconStyleRight={{color:"red"}}
iconElementRight={<IconButton><span className = "material-icons">account_circle</span></IconButton>}
/>
}
but iconStyleRight is giving me the error
Type '{ [x: number]: undefined; color: any; }' is not assignable to type 'string'
No idea why. I've tried many combinations, including adding a style to the <span> element, which is ignored.
Would appreciate correct syntax for making this right icon appear in red, so that I can understand how to apply styles to my icons.
It turns out that the solution is to set the iconStyle attribute of the IconButton component.
Also in my current environment in material-ui.d.ts the typedef of iconStyleRight attribute was erroneously set to 'string', but should have been object, compounding the problem.
All good now.

Im using react Bootstrap Typeahead in my code, problem is whenever I use backspace to remove my selection and when I reach a point where there is no letter, my code breaks and I get below error.
**Uncaught Invariant Violation: One or more options does not have a valid label string. Check the labelKey prop to ensure that it matches the correct option key and provides a string for filtering and display.
My Typeahead Code :
<Typeahead
id="empName"
options={this.state.EmployeeNameOptions}
selected={[this.state.EmployeeName]}
placeholder="Enter Employee Name"
style={{ zIndex: 9999999 }}
onInputChange={text => {
this.setState({
EmployeeName: text,
})
}}
onChange={(e, val) => {
this.handleChange(e, val);
}}
/>
You're using onInputChange and onChange incorrectly. Every time you type inside the input, onInputChange is updating your state and changing the value for selected, leading to unexpected results. Meanwhile, onChange provides an array of the selected values its argument, not an event and value. Try the following instead:
<Typeahead
...
options={this.state.EmployeeNameOptions}
selected={this.state.selectedEmployee}
onChange={(selected) => {
this.setState({ selectedEmployee: selected });
}}
/>
So my question really isn't should I, but rather can I.
If I opt to use styled components for my more common components then I style them once and export.
const MyBlueButton = styled('button')({
backgroundColor: 'blue'
})
Great export that and I have a blue button.
I can also use sx
const MyBlueButton = (props) => {
return <button sx={{backgroundColor: 'blue'}}>{props.children}</button>
}
My question is can I have both, one where I've already made my common component but then want to customize it just a bit unique for one use.
'components/buttons.jsx':
export const MyBlueButton = styled('button')({
backgroundColor: 'blue'
})
--------
'FooBar.jsx':
import {MyBlueButton} from 'components/buttons'
const FooBar = (props) => {
return (
<div>
<p>Some text</p>
<MyBlueButton sx={{fontSize: '20px'}}>Large Blue Button</MyBlueButton>
</div>
)
}
I didn't find anything stating that you couldn't do it. I'm sure you quite possibly can, but can you, and what would be the expected order of css properties?
If I have a styled component with a matching css property in the sx prop would sx win since it's closer to the render? Should I have to worry about injection order with the StyledEngineProvider?
I'm really just hoping I can use a healthy mix of both styled components and one off sx modifications.
I went ahead and made a codesand box to test my idea and it does work to combine both styled wrappers and sx props.
Again probably not for everyday use, but it's nice to know it is possible.
CodeSandbox: https://codesandbox.io/s/keen-roman-s6i7l?file=/src/App.tsx
I have been into such issue;
the way I had to implement the sx props to be passed before passing the component to styled engine was neglecting the props:
const AutoComplete = withThemeProvider(styled(Autocomplete)(autoCompleteStyles));
and when to use it, it gets neglected
<Autocomplete sx={neglectedProps}>
I'm trying to style material-ui DataGrid component to justify the content in the cells. I am reading the material ui docs about styling but I don't seem to doing it correct and frankly find the docs on styling very confusing.
The doc here: https://material-ui.com/customization/components/#overriding-styles-with-classes implies I should be able to do something like this:
const StyledDataGrid = withStyles({
cellCenter: {
justifyContent: "center",
},
})(DataGrid);
<div style={{ height: 300, width: '100%' }}>
<StyledDataGrid rows={rows} columns={columns} />
</div>
However, when I do this, I don't see the style being added to the MuiDataGrid-cellCenter DOM element. Attaching a screenshot which shows the element classes. In the inspector I see that the style isn't being added (and if I add it manually I get the desired results). Am I not using the withStyles function correctly?
So after a bit more messing around, I believe the issue is that the DataGrid component does not support the classes property (which it seems most of the material ui components do). I believe the withStyles usage about is shorthand for passing the classes via the classes prop. Since the prop isn't listed in the API https://material-ui.com/api/data-grid/ I'm assuming this is why it isn't working. I confirmed that I can get the styles working by using a combination of the className parameter with descendant selection.
If someone determines I'm wrong and there is a way to get withStyles working on this component please comment.
const useStyles = makeStyles({
root: {
"& .MuiDataGrid-cellCenter": {
justifyContent: "center"
}
}
});
...
export default function X() {
const classes = useStyles();
return (
...
<DataGrid className={classes.root} checkboxSelection={true} rows={rows} columns={columns} />
...
)
}
ALTERNATIVE SOLUTION: (for others with similar issues)
If you are working within a class and cannot use hooks...
<div>
<DataGrid
rows={rows}
columns={columns}
sx={{
'&.MuiDataGrid-root .MuiDataGrid-cell:focus': {
outline: 'none',
},
}}
/>
</div>
In my app, the expansion arrow has to be in the left side of the panel.
But, by default it's displaying in the right side.
This :
<ExpansionPanelSummary
className={classes.panelSummary}
expandIcon={<ExpandMoreIcon />}
IconButtonProps={{edge: 'start'}}
aria-controls='panel1a-content'
id='panel1a-header'
>
Doesn't made it.
Granted, you can't (easily) change the order in which the components appear in the HTML. However, there is a way using only CSS. ExpansionPanelSummary uses display: flex; you can therefore set the order property on the icon to make it appear to the left of the content.
This can be achieved with either useStyles or withStyles (Or possibly using plain CSS, but I haven't tried it); here's how you'd go about using the latter:
import withStyles from "#material-ui/core/styles/withStyles";
const IconLeftExpansionPanelSummary = withStyles({
expandIcon: {
order: -1
}
})(ExpansionPanelSummary);
You can then write the rest of your code using IconLeftExpansionPanelSummary instead of ExpansionPanelSummary when you want the icon to appear to the left. Don't forget to set IconButtonProps={{edge: 'start'}} on the component for proper spacing.
<AccordionSummary
className={classes.accordionSummary}
classes={{
expandIcon: classes.expandIcon,
expanded: classes.expanded
}}
IconButtonProps={{
disableRipple: true
}}
></AccordionSummary>
You can add class and use flex-direction
accordionSummary: {
flexDirection: 'row-reverse'
}
It's simple
add class on <ExpansionPanelSummary> like this
<ExpansionPanelSummary className={classes.panelSummary}>
add css against this class in jss like this
panelSummary:{flexDirection: "row-reverse"},
In case using css
add class on <ExpansionPanelSummary> like this
<ExpansionPanelSummary className="panelSummary">
add css against this class in jss like this
.panelSummary{flex-direction: row-reverse;}
you can get the expansion panel icon on left by removing it from expandIcon and add it as a children in Summary something like this
<ExpansionPanel defaultExpanded={true}>
<ExpansionPanelSummary aria-controls="panel1a-content">
{this.state.expanded ? <RemoveIcon/> : <ExpandIcon />}
<Typography component='h4' variant='h4'>My Expansion Panel</Typography>
</ExpansionPanelSummary>
<ExpansionPanelsDetails />
</ExpansionPanel>
The challenge is that the order is hardcoded into the codebase and you will not be able to use the ExpansionPanel as is.
If you look at the implementation, you will find the code as below
<div className={clsx(classes.content, { [classes.expanded]: expanded })}>{children}</div>
{expandIcon && (
<IconButton
disabled={disabled}
className={clsx(classes.expandIcon, {
[classes.expanded]: expanded,
})}
edge="end"
component="div"
tabIndex={-1}
aria-hidden
{...IconButtonProps}
>
{expandIcon}
</IconButton>
)}
As you see the <div> contains the text and then the IconButton is displayed.
So, you may have to work with what's provided out of the box or create your own Component based on what material-UI provides.
Hope that helps.
You can modify the CSS class like this:
notice the absolute position, in this way you can move the div that contains the icon whatever position you want with 'left' or 'right' properties
const useStyles = makeStyles((theme) => ({
ExpansionPanelSummaryExpandedIcon: {
'& div.MuiExpansionPanelSummary-expandIcon': {
position: 'absolute',
right: '5%',
},
}
}));
and then use in the ExpansionPanelSummary
<ExpansionPanelSummary
expandIcon={<ExpandMoreIcon />}
aria-controls="panel1-content"
id="panel1bh-header"
className={classes.ExpansionPanelSummaryExpandedIcon}
>

I what to change color of label and text in TextField component.
I am using material-ui#next.
and docs from 0.15 does not work ( I have checked it) .
Can someone give me short example how to override floating label? ( not changing general theme ! )
thanks
From the documentation, when you have a TextField it is, in fact, an abstraction component of several smaller components
Advanced Configuration
It's important to understand that the text field is a simple
abstraction on top of the following components:
FormControl
- InputLabel
List item
Input
FormHelperText
Blockquote
If you wish to alter the properties applied to the native input, you can do as follow:...
In your TextField you can pass props for the Input and Label as follow:
<TextField
defaultValue="react-bootstrap"
label="Bootstrap"
InputProps={{
disableUnderline: true,
classes: {
root: classes.textFieldRoot,
input: classes.textFieldInput,
},
}}
InputLabelProps={{
shrink: true,
className: classes.textFieldFormLabel,
}}
/>
this is taken from the last example given in this page.
